Costco is more than just a warehouse store -- it's a whole vibe. If you're shopping at Costco , you're obviously there for the deals, but have you ever actually stood in the aisle and checked the prices on Costco items vs. other retailers?

Don't worry, I did it for you this month and found six amazing Costco buys for under $25.

1. Natural Vitality Calm Magnesium Citrate Power, 20 ounces

Costco price: $22.99

Amazon price: $35.80

As time ticks ever on, I start to discover, one item at a time, that I am paying way more than I should be for the things I regularly purchase at retailers besides Costco. One of those items is Natural Vitality Calm Magnesium Citrate Powder. No lies, at Costco the bubbly lemon-raspberry drink is a whopping 35.78% off Amazon, and priced at just $22.99 for a 20-ounce jug.

2. Bite Force, Monster Plush Dog Toy Built with Kevlar, 2-count

Costco price: $19.99

Walmart price: $26.99

I love my dogs dearly, but when you live with terriers -- even small ones -- you're constantly replacing toys and always on the hunt for sturdier and sturdier ones that maybe, hopefully, they can't destroy in under an hour. Enter Bite Force toys.

Costco has a two-pack of adorable monster Bite Force dog toys for just $19.99, which is 25.94% off Walmart's best price, and about what I pay for just one sturdy toy of other brands at certain retail pet stores that shall not be named.

3. Caboo Bamboo Paper Towels, 2-Ply, 75 Sheets, 8 Rolls

Costco price: $22.79

Amazon price: $28.79

If you're interested in environmentally friendly paper products, bamboo is where it's at. This highly sustainable material is quick to regrow and spares our precious trees from the ax. But they can also be really expensive, since demand and awareness are still building and they can't always be found in the places you shop in person.

That's OK, because Costco has the planet's back. Caboo Bamboo Paper Towels are just $22.79 for eight rolls of 75 two-ply sheets. That's 20.84% off of Amazon's price, making it more affordable to help do your part for the environment.

4. Refresh Tears Lubricant Eye Drops Multi-Pack, 65 ml.

Costco price: $20.49

Amazon price: $25.49

I will always sing the praises of the Costco pharmacy, even for the over-the-counter items. I have never found more budget -friendly bulk purchases for medication than I have there, and it just keeps giving. When I was checking the website for great deals, I came across these Refresh Tears Lubricant Eye Drops for just $20.49 for four 15 mL bottles and a bonus 5 mL bottle for the road.

I'm not sure how Costco can actually offer pharmacy deals like it does, but it's a boon to humanity in general. These eye drops, for example, are 19.62% off the Amazon price, and the exact same product .

5. Duracell 2000 Lumen Tri-Power Lantern

Costco price: $24.99

Amazon price: $27.89

I was very surprised to see the Duracell 2000 Lumen Tri-Power Lantern on the Costco website, but I also immediately put it in my cart for later. Where I live, ice storms are common in the winter, and a few years ago, I bought an older version of this lantern because I was sick to death of candles for those nights without power.

Now that I have two cats (may we survive the experience), candles just seem incredibly dangerous to have burning under any circumstances, but these Duracell lanterns are so bright and deliver a lot of light on one charge. Currently, they're 11% off of Amazon prices, and I should probably just order another dozen.

6. Duracell 9V Alkaline Batteries, 8-count

Costco price: $18.99

Amazon price: $20.98

Before we get to ice storm season, though, it's going to be fall before we know it. That means bonfires and, most importantly, time to check the smoke alarms. Now, I get it, 9-volt batteries are not a sexy purchase in any way, shape, or form, but knowing that your smoke alarms are ready and willing to warn you of danger is an amazing feeling.

For 9.53% off Amazon's price, you not only get a substantial discount, but you also get a whole year of solid sleep, with no random chirping at 1 a.m.

Costco is the place for deals

Although Costco will never be the cheapest place for everything, it sure will be cheap enough for enough items to make it worth checking. If you're looking for deals under $25, then pick up these six must-have items in August.
